Answer:
125
Step-by-step explanation:
let's see if we can find a pattern
1 = 1 = 1^2
1 + 3 = 4 = 2^2
1 + 3 + 5 = 9 = 3^2
we are starting to see a pattern here, when we add another term, we find the next integer squared.
we can find this last number in our sequence with 2x-1.
so in the next line we should find 4^2. if we plug 4 into 2x-1 we would expect the last term in the sum to be 7.
1 + 3 + 5 + 7 = 16 = 4^2
so 2*63 -1 = 126 - 1 = 125
Isolate m using inverse operations, get m by itself. (addition and subtraction, mult. and div.)

Answer:
15 feets
Step-by-step explanation:
Perimeter of a rectangle = 2(l + w)
l = Length ; w = width
Perimeter, p = 48
Length of all sides
p = 2(l + w)
48 = 2(l + 9)
48 = 2l + 18
48 - 18 = 2l
30 = 2l
l = 30/2
l = 15
Length of the sides = 15 feets
For a cartesian equation

Given r = <span>10 tan(θ) sec(θ)

Therefore,</span>the curve is a parabola opening upward with vertex (0, 0).
